First changes come from Charlton looking to cut off their visitors momentum.

Kayne Ramsay, celebrating his 26th birthday today, is on for Micah Mbick. Ivan Mesik takes Josh Edwards' place.

Brian De Keersmaecker looks to make his Bristol City debut memorable but Billy Koumetio does well to block it out for a corner.

De Keersmaecker then gets to have another go but his effort doesn't do much to threaten the keeper.

Big chance for the away side to double their lead.

Max O'Leary doesn't get a clean punch on a corner from the Blues right and Jhon Solis has his close range shot blocked by three desperate Baggies challengers.

Birmingham make the first change of the day, Liam Millar, who has been away with Canada, is off and Patrick Roberts is on.

It is all Swansea now.

Vladan Kovacevic has to beat away Joseph Opoku's shot at his near post.

The visitors just cannot get hold of the ball.

Chaos in the Norwich area.

Adam Idah's effort is blocked by Vladan Kovacevic and with the goalkeeper on the floor the ball rolls to Joseph Opoku but Ruairi McConville clears off the line.

Opoku had time to pick his spot there.

There were rather loud words of encouragement coming from the home dressing room at half-time. Vitor Matos has got his response.

That's a third goal in as many games for Moussa Yeo

What a great goal and a great response.

If you get a chance, take look at the skill from the three players there. The ball was going nowhere, the ball was flicked on and there was the breakaway and Yeo's there at the back post.

Fantastic goal.

Oof.

Rio Cardines wins a free-kick and whips it into the box. Charlton get a nod on it but can't clear it out the box, allowing Scott Twine to swipe at goal.

It goes well wide. Twine's saying it took a deflection on its way out, the officials disagree.

Rabby Nzingoula gets on the ball and wins a corner for the home side as his, admittedly mishit, shot deflects wide.

The away side clear without too much trouble.

If there's no goals then Vipotnik will have to play some role in this second half.

It's all about chances and untimely outing the ball in the back of the net and Swansea were second best at doing that in the first half.

West Brom are looking to avoid a first home defeat since going down 2-0 to Coventry on 21 February.

The leaders are in trouble.

Could there be derby delight for Birmingham?

Can we find a winner at The Valley?

We are back at it for the second 45.

It is fair to say Simon's opinion is not being universally shared on text today...

Swansea have probably played as well as they can do, but I think Norwich can play better. They have been OK defensively.

They can certainly do better with the ball and I'm sure the manager will be asking that from them in the second half.

It was an equal game early in the game and then as the game wore on Albion had chances, but you've got to take those chances.

Then Blues came back into it and they got the penalty to get the goal.

There's still plenty to play for in this game. Blues are in the ascendency and it's up to James Morrison now to get his team to respond.

Boos at the break from the home fans, but that's aimed at the officials rather than Swansea players as a promising attack was stopped dead by the half-time whistle.

Swansea have responded well after going behind but you can see the boost in belief Norwich have taken from the goal, making the most of some sloppiness from the hosts.

Swansea have had some joy out wide so it will be interesting to see if Philippe Clement makes a tweak to try and counter that threat at half-time - or will Vitor Matos' turn to a pretty stacked subs bench to turn this around?
